The camera module used in the portable electronic devices not only acquires images, but also enables the portable electronic devices to implement functions such as instant video calls. With a trend of increasingly thinner and lighter portable electronic devices and higher imaging quality requirements of the camera modules, more stringent requirements are imposed on overall size of the camera module and imaging capabilities of the camera module. That is, development trend of the portable electronic devices requires the camera module to further improve and enhance the imaging capability on the basis of reducing the size.
[0003] It is well known that improvement of the imaging capability of the camera module is based on configuration of a photosensitive element with a larger imaging area and more passive electronic components such as driving resistors and capacitors for the camera module, because the camera module needs to be configured with photosensitive element with a larger imaging area and more passive electronic components, the camera module is required to reduce the size of the camera module only by improving packaging process. A commonly used camera module packaging process is a COB (Chip On Board) packaging process, that is, a circuit board, a photosensitive element, a bracket, or the like of the camera module are respectively fabricated, and then passive electronic components, photosensitive elements, and brackets are sequentially mounted on the circuit board, in order to ensure the imaging quality of the camera module, it is necessary to fill glue between each two components, for example, fill glue between the bracket and the circuit board to mount the bracket on the circuit board, and the leveling of the bracket and the circuit board is achieved by the glue. Therefore, the size of the camera module cannot be effectively reduced by the COB packaging process, and packaging efficiency of the camera module is relatively low.

[0015] The following description is presented to disclose the present invention to enable those skilled in the art to practice the present invention. The preferred embodiments in the following description are by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention as defined in the following description may be applied to other embodiments, modifications, improvements, equivalents, and other embodiments without departing from the spirit and scope of the invention.
[0016] It should be understood by those skilled in the art that in the disclosure of the present invention, The orientation or positional relationship of the indications of the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "upright", "horizontal", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, which is merely for the convenience of describing the present invention and simplifying the description rather than indicating or implying that the device or element referred to must have a particular orientation, constructed and operated in a particular orientation. Therefore, the above terms are not to be construed as limiting the present invention.
[0017] It will be understood that the term "a" is understood to mean "at least one" or "one or more", that is, in one embodiment, the number of one element may be one, and in other embodiments, the number of the element can be multiple, and the term "a" cannot be construed as limiting the quantity.
[0018] Fig. 1 to Fig. 7 show a camera module 100 according to a preferred embodiment of the present invention. The camera module 100 includes a camera lens 10 and a molding photosensitive assembly 20. The molding photosensitive assembly 20 further includes a photosensitive element 21, a circuit board 22, a molding base 23, a set of leads 24, a supporting element 25, a plurality of electronic components 26, and a lens 27. Both ends of each of the leads 24 respectively extend to be connected to a non-photosensitive area 213 of the photosensitive element 21 and the circuit board 22, and the molding base 23 is integrally molded on the circuit board 22 so that the molding base 23, the circuit board 22, and the lens 27 forms a unitary structure. Each of the electronic components 26 may be attached to the circuit board 22 by a process such as an SMT (Surface Mount Technology).
[0019] The camera lens 10 and the lens 27 are disposed on a photosensitive path of the photosensitive element 21 of the molding photosensitive assembly 20. Light reflected by the object enters inside of the camera module 100 from the camera lens 10 and the lens 27 to be subsequently received and photo-electrically converted by the photosensitive element 21, thereby acquiring an image associated with the object. In the present invention, the molding process in which the molding base 23 is molded on the thermohardening lens 27 is defined as a MOL (molding on lens) molding process so as to distinguished from the traditional COB (chip on board) molding process. The disposition of the lens 27 can reduce the optical TTL (a distance from a camera lens plane above a light through hole of the camera lens to a photosensitive plane of chip), thereby further reducing the size of the camera module 100 without affecting optical performance. It satisfies the demand for electronic device to equip a small-sized camera module 100. At the same time, the disposition of the lens 27 can also reduce stain sensitivity. For example, in one embodiment, 50% of stain sensitivity can be reduced. That is, preferably, the camera lens 10 includes a plurality of camera lens elements, the camera lens element of the camera lens 10 and the lens 27 form an optical system, and light rays passing through the optical system are converged to the photosensitive element 21. That is, the conventional camera lens is implemented in two parts in the present invention, one part is the camera lens 10, the other part is the lens 27, the lens 27 is a camera lens enableing to refract light, the camera lens 10 and the lens 27 play the role of refracting light together, thereby converging light to the photosensitive element 21, which can effectively reduce the TTL of the entire optical system. In another aspect, in the present invention, the camera lens 10 and the lens 27 form a camera lens assembly, one of the lens of the camera lens assembly becomes an external lens, that is, the lens 27, and the lens 27 is integrally packaged by the molding base 23 so that the size of the camera module can be reduced.
[0020] In this preferred embodiment of the present invention, preferably, the lens 27 is implemented as a lens of thermohardening properties, i.e. the lens is implemented as a thermohardening lens such that the lens 27 is capable of withstanding ambient temperature in a molding process as undergoing the molding process. For example, it is capable of withstanding a molding ambient temperature of 175 ° C in the molding process of an embodiment. That is, before the molding process, the high temperature resistant and thermohardening lens 27 is connected to the supporting element 25 and placed together with the circuit board 22 and the photosensitive element 21 in a molding die, a solidified molding material of fluid state is around the supporting element 25 and the outer surface of the lens 27 to mold the molding base 23 molded integrally, so that the molding base 23 can be integrally molded on the circuit board 22, that is, the molding base 23, the circuit board 22 and the lens 27 forms a unitary structure. It will be understood by those skilled in the art that the lens 27 of the present invention may be not only a thermohardening lens but also a lens with other natures, and the present invention is not limited thereto.
[0021] Further, the lens 27 includes a lens body 271 and a lens periphery 272 disposed around the lens body 271. Since the lens 27 is a precise optical element, the edge of the lens body 271 is thin. The lens periphery 272 disposed at the edge of the lens body 271 and integrally connected is a thickened bracket design capable of carrying the lens body 271 so as not to affect the optical performance of the lens body 271 while enabling the lens body 27 to be integrally molded to be connected to the molding base 23 in a molding die. That is, the lens periphery 272 of the lens 27 is disposed in the non-photosensitive area 213 of the photosensitive element 21 before the molding base 23 is molded, the lens body 271 of the lens 27 is disposed on a photosensitive path of the photosensitive element 21 of the molding photosensitive assembly 20; after the molding base 23 is molded, the molding base 23 embeds the circuit board 22, the non-photosensitive area 213 of the photosensitive element 21, a part of the supporting element 25, and the lens periphery 272 of the lens 27 to form the molding photosensitive assembly 20.
[0022] It is to be noted that the supporting element 25 can effectively improve the product yield of the camera module 100 and improve the imaging quality of the camera module 100. Further, the supporting element 25 includes an annular supporting main body 251 and has a through hole 252, wherein the supporting main body 251 is disposed on the non-photosensitive area 213 of the photosensitive element 21 such that a photosensitive area 212 of the photosensitive element 21 corresponds to the through hole 252 of the supporting element 25 and the lens body 271 of the lens 27, so that the supporting main body 251 and the lens 27 can protect the photosensitive area 212 of the photosensitive element 21 during the molding process. Further, the supporting element 25 has a top surface 2501, an inner side surface 2502 and an outer side surface 2503, wherein two ends of the top surface 2501 are respectively connected to the inner side surface 2502 and the outer side surface 2503. A side of the supporting element 25 facing the photosensitive element 21 is defined as the inner side surface 2502 of the supporting element 25, and a side of the supporting element 25 facing the circuit board 22 is defined as the outer side surface 2503 of the supporting element 25. The inner side surface 2502 of the supporting element 25 is used to form the through hole 252 of the supporting element 25.
[0023] It is to be noted that the lens periphery 272 has a top surface 2721, a bottom surface 2722 and an outer peripheral surface 2723. Two ends of the outer peripheral surface 2733 of the lens periphery 272 are respectively connected to the top surface 2721 and the bottom surface 2722 of the lens periphery 272. That is, a side of the lens periphery 272 facing the circuit board 22 is defined as the outer peripheral surface 2723 of the lens periphery 272. It is to be noted that the lens body 271 has an outer lens surface 2711 and an inner lens surface 2712. That is, a side of the lens body 271 facing the photosensitive element 21 is defined as the inner lens surface 2712 of the lens body 271, and a side connected to the top surface 2721 of the lens periphery 272 is defined as the outer lens surface 2711 of the lens body 271.
[0024] Further, after the lens 27 is attached to the supporting main body 251, it is placed in a molding die together with the circuit board 22 and the photosensitive element 21 to perform a molding process. Thermocuring molding material of fluid state is thermally cured to form the molding base 23, and the molding base 23 embeds the outer side surface 2503 of the supporting main body 251 and the outer peripheral surface 2723 of the lens periphery 271 after being molded. Of course, in other embodiments, the molding base 23 embeds all or a part of the top surface 2721 of the lens periphery 271 after being molded.
[0025] Further, the photosensitive element 21 includes the photosensitive area 212 and the non-photosensitive area 213, wherein the photosensitive area 212 and the non-photosensitive area 213 of the photosensitive element 21 are integrally formed, and the photosensitive area 212 is located in the center of the photosensitive element 21, the non-photosensitive area 213 is located at outer part of the photosensitive element 21, and the non-photosensitive area 213 surrounds the photosensitive area 212. After light reflected by an object enters inside of the camera module 100 from the camera lens 10, it can be received and photo-electrically converted by the photosensitive area 212 of the photosensitive element 21 to acquire an image associated with the object.
[0026] Further, the photosensitive element 21 has a set of chip connectors 211, and the circuit board 22 has a set of circuit board connectors 221, wherein both ends of each of the leads 24 can be respectively connected to each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22, the photosensitive element 21 and the circuit board 22 are connected in such a manner as described above. In an embodiment of the present invention, each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22 may be a connection disk, that is, each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22 may be respectively in a disk shape for connecting both ends of each of the leads 24 to each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22. In another example of the present invention, each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22 may be spherical, for example, a solder paste or other solder material is spotted on the photosensitive element 21 and the circuit board 22 to form the chip connector 211 of the photosensitive element 21 and the circuit board connector 221 of the circuit board 22, respectively. Nevertheless, the shape of the chip connector 211 of the photosensitive element 21 and the circuit board connector 221 of the circuit board 22 are not limit in the content and scope of the present invention.
[0027] It will be understood by those skilled in the art that each of the chip connectors 211 of the photosensitive element 21 is disposed in the non-photosensitive area 213 of the photosensitive element 21. In addition, the non-photosensitive area 213 of the photosensitive element 21 has a chip inner side portion 2131, a chip connection portion 2132, and a chip outer side portion 2133, wherein the chip inner side portion 2131 surrounds the photosensitive area 212, both ends of the chip connection portion 2132 extend and are connected to the chip inner side portion 2131 and the chip outer side portion 2132, respectively. That is, an area of the non-photosensitive area 213 from the position where the chip connector 211 is disposed to the position of an edge of the photosensitive area 212 is defined as the chip inner side portion 2131, and an area of the non-photosensitive area where the chip connector 211 is disposed is defined as the chip connection portion 2132, and an area of the non-photosensitive area 213 from the position where the chip connector 211 is disposed to the position of the outer edge of the photosensitive element 21 is defined as the chip outer side portion 2132. In other words, from the top view of the photosensitive element 21, the photosensitive element 21 is, in order from the outside to the inside, the chip outer side portion 2133, the chip connection portion 2132, the chip inner side portion 2131 and the photosensitive area 212.
[0028] In addition, the circuit board 22 includes a flat chip attaching area 222 and an edge area 223, wherein the edge area 223 is integrally formed with the chip attaching area 222, and the edge area 223 is located on the periphery of the chip attaching area 222. The chip attaching area 222 is used to attach the photosensitive element 21, and the circuit board connector 221 is disposed in the edge area 223. The edge area 223 of the circuit board 22 has a circuit board inner side portion 2231, a circuit board connection portion 2232, and a circuit board outer side portion 2233, wherein the circuit board inner side portion 2231 surrounds the chip attaching area 222. Both ends of the circuit board connection portion 2232 respectively extend and are connected to the circuit board inner side portion 2231 and the circuit board outer side portion 2233. That is, the area of the edge area 223 from a position where the circuit board connector 221 is disposed to a position of an edge of the chip attaching area 222 is defined as the board inner side portion 2231, the area of the edge area 223 where the circuit board connector 221 is disposed is defined as the circuit board connection portion 2232, and the area of the edge area 223 from the position where the circuit board connector 221 is disposed to the position of the outer edge of the edge area 223 is defined as the circuit board outer side portion 2233. In other words, from the top view of the circuit board 22, the circuit board 22 is, in order from the outside to the inside, the circuit board outer side portion 2233, the circuit board connection portion 2232, the circuit board inner side portion 2231 and the chip attaching area 222. The type of the lead 24 is not limited in the camera module 100 of the present invention. For example, in a specific embodiment, the lead 24 can be implemented as a gold wire, that is, the photosensitive element 21 and the circuit board 22 can be connected together by a gold wire, so that the electrical signal can be further transmitted to the circuit board 22 through the lead 24 after the photosensitive element 21 converts an optical signal into an electrical signal. It can be understood by those skilled in the art that in other examples of the camera module 100, the lead 24 can also be implemented as any material capable of realizing the transmission of the electrical signal between the photosensitive element 21 and the circuit board 22.
[0029] It is to be noted that each of the electronic components 26 is attached to the edge area 223 of the circuit board 22. Preferably, each of the electronic components 26 is attached to the circuit board outer side portion 2233 of the edge area 223. The photosensitive element 21 and each of the electronic components 26 may be attached to the same side or opposite sides of the circuit board 22, for example, in a specific embodiment, the photosensitive element 21 and each of the electronic components 26 is attached to the same side of the circuit board 22, and the photosensitive element 21 is attached to the chip attaching area 222 of the circuit board 22, and each of the electronic components 26 is attached to the edge area 223 of the circuit board 22. After the molding base 23 is integrally molded to the circuit board 22, the molding base 23 embeds each of the electronic components 26 to isolate adjacent ones and isolate the electronic component 26 and the photosensitive element 21, so that in the camera module 100 of the present invention, even when the distance between the adjacent electronic components 26 is relatively close, the molding base 23 can prevent adjacent electronic components 26 from contacting or interfering with each other, and the manner in which the molding base 23 embeds the electronic component 26 can also prevent contaminants generated on the surface of the electronic component 26 from contaminating the photosensitive area 212 of the photosensitive element 21, thereby reducing the volume of the camera module 100 and improving the imaging quality of the camera module 100. That is, the manner in which the molding base 23 embeds the electronic component 26 in the camera module 100 of the present invention makes the circuit board 22 of a small area to be capable of being attached more electronic component 26. It is to be noted that the types of electronic components 26 include, but are not limited to, resistors, capacitors, drivers and the like.
[0030] Further, as shown in FIG. 7, the camera module 100 further includes at least one filter element 40. In the preferred embodiment of the present invention, the filter element 40 is disposed at the bottom of the camera lens 10. That is, the filter element 40 is assembled to the camera lens 10. The optical lens inside the camera lens 10 are sequentially arranged, and the filter element 40 is located in the optical path of the camera lens 10. After the molding photosensitive assembly 20 is molded and integrally packaged, the filter element 40 and the camera lens 10 are attached to the molding photosensitive assembly 20 to be assembled to form the camera module 100. The filter element 40 is located in the photosensitive path of the photosensitive element 21. The light reflected by the object, which is from the optical lens of the camera lens 10 and filtered by the filter element 40 to enter the inside of the camera module 100, can be received and photo-electrically converted by the photosensitive element 21. That is, the filter element 40 can filter stray light, such as an infrared part, from the light reflected by the object in each of the optical lens of the camera lens 10, and in this manner, the imaging quality of the camera module 100 can be improved.
[0031] It will be understood by those skilled in the art that in different examples of the camera module 100, the filter elements 40 can be implemented in different types, for example, the filter elements 40 can be implemented as infrared cut filters, a full transmissive spectral filter and other filters, or a combination of a plurality of filters, for example, the filter element 40 can be implemented as a combination of an infrared cut filter and a full transmissive spectral filter. That is, the infrared cut filter and the full transmissive spectral filter can be switched to be selectively located on the photosensitive path of the photosensitive element 21, for example, when the camera module 100 is used in a light sufficient environment such as daytime, the infrared cut filter can be switched to the photosensitive path of the photosensitive element 21 to filter infrared rays from the light reflected by the object that enters the camera module 100 through the infrared cut filter, when the camera module 100 is used in a dark environment such as at night, the full transmissive spectral filter may be switched to the photosensitive path of the photosensitive element 21 to allow the transmittion of the infrared portion of the light reflected by the object that enters the camera module 100.
[0032] It is to be noted that the mounting position of the filter element 40 has various variant embodiments in different embodiments. The filter element 40 described in Fig. 7 is disposed at the bottom part inside the camera lens 10. In other embodiments, the filter element 40 is disposed at top of the molding base 23. Both of these dispositions are performed by mounting the filter element 40 after the molding photosensitive assembly 20 is molded integrally. In other embodiments, the filter element 40 and the molding photosensitive assembly 20 are molded and assembled together in a molding die. That is, in other embodiments, the peripheral edge of the filter element 40 may be covered by the supporting element 25 and secured between the photosensitive element 21 and the lens 27. When the camera module 100 is not provided with the supporting element 25, the filter element 40 is attached to the photosensitive element 21 and located between the lens 27 and the photosensitive element 21. The latter two dispositions are in that the filter element 40 and the photosensitive element 21, the circuit board 22, the supporting element 25 and the lens 27 are placed together in a molding die, the molding base 23 is formed after being molded by the MOL process, so as to being assembled to form the camera module 100 after the camera lens 10 or a driver 30 driving the camera lens 10 is mounted. Various variations in position of the filter element 40 will be disclosed in detail in subsequent embodiments.
[0033] It is to be noted that the lens 27 can be a convex lens and has a function of converging light. Since the filter element 40 does not cause refraction of light, the lens 27 implemented as a convex lens makes image smaller. The particles (stains) on the filter element 40 tend to cause the photosensitive element 21 to form a large stain point in the image, and the closer to the photosensitive element 21, the larger the imaged stain point is. Therefore, in the MOL process of the present invention, the lens 27 is disposed at a lower part of the camera lens 10, and the filter element 40 is disposed at a bottom portion inside the camera lens 10. That is, the MOL process of the present invention can move the filter element away from the photosensitive element 21 without affecting the convergence of the light of the lens 27 implemented as a convex lens, thereby making the image of the stained spot smaller.
[0034] It is to be noted that, preferably, the lens periphery 272 of the lens 27 has a square step shape.
[0035] It is to be noted that in the MOL molding process of the present invention, the supporting main body 251 also has various variant embodiments. For example, in one embodiment, the supporting main body 251 covers entire of the lead 24, the circuit board outer side portion 2233 of the edge area 223, the circuit board connection portion 2232, the circuit board inner side portion 2231, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213; and in another embodiment, the supporting main body 251 covers a part of the lead 24, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213; and in another embodiment, the supporting main body 251 covers a part of the lead 24, the circuit board inner side portion 2231 of the edge area 223, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213; and for example, in an embodiment, The supporting main body 251 covers a part of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner side portion 2231 of the edge area 223; for example, in an embodiment, the supporting main body 251 covers a part of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232, the circuit board inner side portion 2231 of the edge area 223, and the chip outer side portion 2133 of the non-photosensitive area 213; in another embodiment, the supporting main body 251 covers the circuit board inner side portion 2231 of the edge portion 223 and the chip outer side portion 2133 of the non-photosensitive area 213; In one embodiment, the supporting main body 251 is formed only at the chip inner side portion 2131 of the non-photosensitive area 213; and in another embodiment, the supporting main body 251 is formed only at the circuit board outer side portion 2233 of the edge area 223. Various variant embodiments of the supporting main body 251 will be disclosed in detail in the following embodiments.
[0036] It will be understood by those skilled in the art that the variant embodiments of the filter element 40 in position discribed above and each of the variant embodiments of the supporting main body 251 are merely exemplified in the present invention, and other reasonable variant embodiments are possible, the present invention is not limited in this respect.
[0037] It is to be noted that, in an embodiment, the camera module 100 can be implemented as a fixed focus camera module, wherein the camera module 100 maintains the camera lens 10 in a photosensitive path of the photosensitive element 21 by a molding body 232 assembled to the molding base 23. It is to be noted that, in an embodiment, the camera module 100 can be implemented as a zoom camera module, wherein the camera module 100 changes the distance between the camera lens 10 and the photosensitive element 21 to adjust the focal length of the camera module. The camera module 100 is implemented as a zoom camera module as shown in Fig. 7. The camera module 100 further includes the driver 30, wherein the camera lenses 10 are respectively disposed correspondingly to the drivers 30, the drivers 30 are respectively assembled to the molding bases 23, and the drivers 30 are electrically connected to the circuit board 22, respectively, to enable the driver 30 to drive the camera lens 10 to move back and forth along the photosensitive path of the photosensitive element 21 after the circuit board 22 transmits power and control signals to the driver 30 so as to adjust the focal length of the camera module 100. That is, the camera lens 10 is drivably disposed to the driver 30. It is to be noted that the type of the driver 30 is not limited in the camera module 100 of the present invention. For example, in another embodiment, the driver 30 can be implemented as any driver, such as a voice coil motor, that is capable of driving the camera lens 10 along the photosensitive path of the photosensitive element 21 to generate a displacement, wherein the driver 30 is capable of receiving electrical energy and control signals to be in an operational state.
[0038] It is to be noted that when the camera module 100 is implemented as a fixed focus camera module, the molding body 232 is implemented as a lens bracket for assembling the camera lens 10, and the camera lens 10 is directly mounted on the molding body 232 which is implemented as a lens bracket after the photosensitive element 20 is integrally formed, thereby simplifying the assembly process of the camera module 100. Variations of this aspect of the present invention will be disclosed in detail in the following embodiments.
[0039] Hereinafter, that the molding photosensitive assembly 20 is integrally formed by the MOL molding process and assembled to form the camera module 100 are disclosed in detail from the respective embodiments.
[0040] In a preferred embodiment of the camera module 100 of the present invention as shown in Fig. 1 to Fig. 7, the bottom surface 2722 of the lens 27 is attached to the top surface 2501 of the supporting element 25, and the supporting main body 251 covers entire of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner side portion 2231 of the edge area 223, and the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213, the filter element 40 is disposed at a bottom portion inside the camera lens 10. In this preferred embodiment of the present invention, the camera lens 10 is mounted after the molding photosensitive assembly 20 is integrally molded.
[0041] Further, the manufacturing steps of the camera module 100 and the manufacturing steps of the molding photosensitive assembly 20 will be described. As shown in Fig. 2, the photosensitive element 21 is attached to the chip attaching area 222 of the circuit board 22, and the chip connector 211 of the non-photosensitive area 213 of the photosensitive element 21 and the circuit board connector 221 of the edge area 223 of the circuit board 22 is connected by a set of the leads 24. Further, the electronic component 26 is attached to the circuit board outer side portion 2233 of the edge area 223 of the circuit board 22. Preferably, both ends of a set of the leads 24 are respectively connected to the photosensitive element 21 and the circuit board 22, wherein each of the leads 24 protrudes arcually from the upper surface of the photosensitive element 21, and the curved curvature of the lead 24 is maintained in a rounded state, which is advantageous for ensuring the ability of the lead 24 to transmit the electrical signal between the photosensitive element 21 and the circuit board 22, wherein each of the leads 24 is arranged between the photosensitive element 21 and the circuit board 22, for example, each of the leads 24 may be equally spaced. It can be understood by those skilled in the art that, in other embodiments, a plurality of the photosensitive elements 21 may be attached to different positions of one circuit board 22 to subsequently fabricate a dual lens camera module or array camera module, for example, in a embodiment shown in Fig. 14, a plurality of the circuit boards 22 are placed together to form a circuit board jointed board 2200, and then each of the photosensitive elements 21 is respectively attached to the circuit board 22 at a corresponding position of the circuit board jointed board to subsequently separate the circuit board jointed board 2200, but the present invention is not limited in this respect.
[0042] As shown in Fig. 2 and Fig. 3, on one hand, the supporting main body 251 can prevent the connection position of the lead 24 and the chip connector 211 from coming into contact with the thermocuring material for forming the molding base 23, so as to prevent the thermocuring material of fluid state from causing deformation of the end of the lead 24 for connecting the chip connector 211 or the detachment of the lead 24 from the chip connector 211. On the other hand, the supporting main body 251 and the lens periphery 272 of the lens 27 are connected together to isolate the connection position of the lead 24 and the chip connector 211 from the thermocuring material. That is, since the supporting main body 251 and the lens periphery 272 of the lens 27 are connected together, the inner side surface 2502 of the supporting element 25 and the lens inner surface 2712 of the lens body 271 form a closed space 2700, such that when the MOL molding process is performed, the thermocuring material of fluid state is prevented from entering the closed space 2700, thereby avoiding affecting the light-passing path and also reducing the stain sensitivity. In one embodiment, the supporting main body 251 may be formed by disposing glue at the non-photosensitive area 213 of the photosensitive element 21 and formed after the glue is initially cured. After the preliminary curing, the lens 27 is further disposed and further cured to finally form the supporting main body 251. After the supporting main body 251 is formed, the inner side surface 2502 of the supporting main body 251 forms the through hole 252, and the photosensitive area 212 of the photosensitive element 21 corresponds to the through hole 252 and the lens body 271 of the thermohardening lens 27. In addition, the supporting main body 251 formed of glue may also have a viscosity for subsequently adhering contaminants such as dust, thereby preventing the contaminants from contaminating the photosensitive area 212 of the photosensitive element 21 to cause the occurance of a stain point in the photosensitive area 212 of the photosensitive element 21 to further ensure the image quality of the camera module. In other embodiments, the lens periphery 272 of the lens 27 is attached to the supporting main body 251 of the supporting element 25 after the supporting element 25 is fully cured, and the present invention is not limited thereto.
[0043] As shown in Fig. 4, at the time of performing the MOL molding process, the molding material of the thermocuring material which is implemented in fluid state is formed into the molding base 23 which is at least integrally molded on the circuit board 22 after curing by a molding die 900. In this manner, the size of the camera module 100 and the assembly error of the camera module can be reduced, thereby making the structure of the camera module 100 more compact and improving the image quality of the camera module 100. Moreover, since the lens 27 is disposed on the photosensitive element 21 through the supporting element 25, the optical TTL is reduced, the structure of the camera module 100 is more compact, and the size of the camera module 100 of the electronic device is satisfied.
[0044] Specifically, the molding die 900 includes an upper die 901 and a lower die 902, wherein at least one of the upper die 901 and the lower die 902 can be moved to enable the upper die 901 and the lower die 902 to be clamped, and at least one molding space 903 is formed between the upper die 901 and the lower die 902, wherein the molding base 23 is formed by adding the molding material to the molding space 903 after curing.
[0045] The photosensitive element 21 and the circuit board 22 are connected by a set of the leads 24, the supporting main body 251 is formed on the non-photosensitive area 213 of the photosensitive element 21 to cover entire of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner side portion 2231 of the edge area 223, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2132 of the non-photosensitive area 213, the lens 27 is disposed on the supporting main body 251, so that a semi-finished product of the molding photosensitive assembly 20 is fabricated, the semi-finished product of the molding photosensitive assembly 20 is placed on the lower die 902 of the molding die 900, the upper die 901 and/or the lower die 901 of the molding die 900 are operated, so that the upper die 901 and the lower die 902 are clamped, thereby the molding space 903 is formed between the upper die 901 and the lower die 902, wherein the press-fitted surface 9011 of the upper die 901 is in contact with lens inner surface 2712 of the lens body 271 of the lens 27, and the lens 27 is supported upward by the supporting main body 251. In this preferred embodiment of the present invention, the exterior of the circuit board 22, the non-photosensitive area 213 of the photosensitive element 21, a part of the supporting element 25 and the outer peripheral surface 2723 of the lens periphery 272 of the lens 27 are located in the molding space 903 of the molding die 900, so that when the molding base 23 is molded in the molding space 903, the molding base 23 embeds the exterior of the circuit board 22, the non-photosensitive area 213 of the photosensitive element 21, a part of the supporting element 25 and the outer peripheral surface 2723 of the lens periphery 272. Preferably, in the molding photosensitive assembly 20 formed as shown in Fig. 2, since the press-fitted surface 9011 of the upper die 901 of the molding die 900 does not completely cover the lens inner surface 2712 of the lens body 271 in the MOL molding process, thus, the molding base 23 formed also covers a part of the top surface 2721 of the lens periphery 272.
[0046] Therefore, it will be understood by those skilled in the art that the molding space 903 of the molding die 900 may be an annular space to form a annular molding base 23 after the molding material is added to the molding space 903 and cured.
[0047] It is to be noted that the fluid-state molding material according to the present invention may be a liquid material or a solid particulate material or a mixed material of liquid and solid particles. It is to be understood that whether the molding material is implemented as a liquid material or as a solid particulate material or as a mixed material of liquid and solid particles, after being added to the molding space 903 of the molding die 900, it can be cured to form the molding base 23. For example, in this specific example of the present invention, the fluid-state molding material is implemented as a thermocuring material such as a liquid, wherein the molding material is cured after being added to the molding space 903 of the molding die 900 to form the molding base 23. It is to be noted that, when the fluid-state molding material is added to the molding space 903 of the molding die 900, the curing manner of the fluid-state molding material does not limit the content and scope of the present invention.
[0048] It is to be noted that the medium forming the supporting element 25 and the medium forming the molding base 23 are of different materials. The supporting element 25 can be formed by an elastic medium, so that the molded supporting element 25 has a certain elasticity, and the supporting element 25 can also be formed by a rigid medium, and the present invention is not limited thereto. As shown in Fig. 5 and Fig. 6, the supporting main body 251 is disposed along the non-photosensitive area 213 of the photosensitive element 21, and the lens periphery 272 of the lens 27 is closely attached to the supporting main body 251 to form the closed space 2700 such that the supporting main body 251 and the lens body 271 of the lens 27 can prevent the molding material from entering into the closed space 2700 after the molding material is added to the molding space 903 of the molding die 900, that is, prevent it from entering the photosensitive area 212 of the photosensitive element 21, so that after the molding material is cured to form the molded base 23 and demolded, the molding base 23 is further formed into a molding hole 231 to correspond to the photosensitive area 212 of the photosensitive element 21, so that, subsequently, the molding hole 231 of the molding base 23 allows light to pass through to be received and photo-electrically converted by the photosensitive area 212 of the photosensitive element 21. That is, since the molding material does not enter the closed space 2700, after demolding, the molding hole 231 is formed between the outer surface 2711 of the lens body 271 of the lens 27 and the press-fitted surface 9011. That is, the molding base 23 includes the molding main body 232 and has the molding hole 231 which provides a light path for the optical camera lens 10 and the photosensitive element 21. Therefore, after the light reflected by the object enters the inside of the camera module from the optical camera lens 10, the light passes through the molding hole 231 of the molding base 23 to be received and photo-electrically converted by the photosensitive area 212 of the photosensitive element 21.
[0049] As manufacturing the molding photosensitive assembly 20, the photosensitive element 21 is first attached to the circuit board 22, and then the supporting element 25 is formed, and further, the lens 27 is disposed on the supporting element 25, the circuit board 22, the photosensitive element 21 and the lens 27 are molded to form the molding base 23, thereby be molded to form the molding photosensitive assembly 20. At the time of molding, since the closed space 2700 is formed between the lens 27 and the photosensitive element 21, damage of the photosensitive element 21 by the molding die can be prevented, and since the distance between the lens 27 and the photosensitive element 21 is reduced, the back focal length of the camera module 100 assembled by them can be reduced, thereby reducing the height of the camera module 100. In another aspect, since additional supporting component is not required for lens 27, it further reduces the thickness of the camera module 100 to some extent. After molding to form the photosensitive assembly 20, the driver 30 and the camera lens 10 are assembled on the molding base 23 to form the camera module 100, wherein, in the preferred embodiment, the filter element 40 is disposed at the bottom inside the camera lens 10. It will be understood by those skilled in the art that, in other variant embodiments based on the preferred embodiment, after molding to form the molding photosensitive assembly 20, the camera lens 10 or a lens frame supporting the camera lens 10 is directly assembled on the molding base 23, that is, the driver 30 may not be disposed. The above is by way of example only, and the present invention is not limited thereto.
[0050] Fig. 8B illustrates a variant embodiment based on the preferred embodiment of the present invention, illustrating that the molding photosensitive assembly 20 and the filter element 40 are assembled to form a camera module 108. In this variant embodiment, the camera module 108 is similar in structure to the camera module 100 in the preferred embodiment, except that the filter elements 40 of the camera module 108 in Fig. 8B are disposed at different positions. In this variant embodiment, the filter element 40 is not provided at the bottom inside the camera lens 10 of the camera module 108, but the filter element 40 is assembled on the top surface of the molding base 23, such that the filter element 40 encloses the molding hole 231 of the molding base 23, so that light entering the interior of the camera module 108 from the optical camera lens 10 can be further filtered by the filter element 40 to improve the imaging quality of the camera module 108. That is, the top surface of the molding base 23 forms an inner side surface 233 and an outer side surface 234, and in the embodiment shown in Fig. 8B, the plane in which the inner side surface 233 of the molding base 23 is located may be lower than the plane in which the outer side surface 234 is located, so that the top surface of the molding base 23 forms a stepped surface, that is, the plane in which the inner side surface 233 of the molding base 23 is located may be lower than the plane in which the outer side surface 234 is located to form a groove 235 of the molding base 23, wherein the filter element 40 assembled to the inner side surface 233 of the molding base 23 is accommodated within the groove 235 of the molding base 23, the driver 30 is assembled to the outer side surface 234 of the molding base 23 to enable the optical camera lens 10 assembled to the driver 30 further to be held in the photosensitive path of the photosensitive element 21, thereby producing the camera module 108. It will be understood by those skilled in the art that, in other embodiments, the inner side surface 233 and the outer side surface 234 of the molding base 23 are in a same plane to allow the top surface of the molding base 23 to form a flat plane, wherein the filter element 40 is assembled to the inner side surface 233 of the molding base 23, the driver 30 or the camera lens 10 is assembled to the outer side surface 234 of the molding base 23, or the camera lens 10 is assembled directly to the outer side surface 234 of the molding base 23. The above structure of the molding base 23 of the present invention is merely an example, and the present invention is not limited thereto.
[0051] As manufacturing the molding photosensitive assembly 20, the photosensitive element 21 is first attached to the circuit board 22, and then the supporting element 25 is formed, and further, the lens 27 is disposed on the supporting element 25, such that the circuit board 22, the photosensitive element 21 and the lens 27 are molded in a molding die to form the molding base 23, thereby forming the molding photosensitive assembly 20. Further, the driver 30 and the camera lens 10 are assembled after the filter element 40 is assembled to the top surface of the molding base 23, thereby assembling and forming the camera module 108.
[0052] As shown in Fig. 9, a camera module 109 according to another variant embodiment of the preferred embodiment of the present invention is described, the camera module 109 in the variant embodiment and the camera module 100 in the preferred embodiment are similar in structure, except that the disposition and assembly order of the filter elements 40 of the camera module 109 in Fig. 9 are different. In the preferred embodiment of Fig. 7, the molding photosensitive assembly 20 is molded first, and then the filter element 40 disposed at the bottom of the camera lens and the camera lens 10 are assembled together on the molding base 23. In the camera module 109 of the variant embodiment shown in Fig. 9, the filter element 40, the lens 27, the supporting element 25, the photosensitive element 21 and the circuit board 22 are placed together in a molding die to form the molding base 23, and then the driver 30 and the camera lens 10 are attached to the molding base 23. Specifically, in this variant embodiment shown in Fig. 9 of the present invention, the filter element 40 is laminated on the photosensitive element 21. A surface attach process can be used here. In order to enhance the stability of the filter element 40 in the photosensitive element 21, in an embodiment, the edge of the filter element 40 is fixedly connected by the supporting element 25 and attach to the photosensitive element 21, thereby The filter element 40 is fixed between the supporting element 25 and the photosensitive element 21. The outer side surface 2503 of the supporting main body 251, the outer peripheral surface 2723 of the lens periphery 272 are molded to the molding base 23, the supporting element 25, the photosensitive element 21 and the lens 27, the circuit board 22 and the electronic component 26 are molded by the molding main body 232 of the molding base 23. It is to be noted that, in this embodiment, the filter element 40 covers the photosensitive element 21, and the photosensitive element 21 is isolated from the closed space 2700 and the external environment, thereby, the photosensitive element 21 is prevented from being damaged and dust entering the closed space 2700 is prevented from coming into contact with the photosensitive member 21, and stain sensitivity is lowered.
[0053] When the molding photosensitive assembly 20 is manufactured, the photosensitive element 21 is attached to the circuit board 22 firstly, and the filter element 40 is attached to the photosensitive element 21, and then the supporting element 25 is formed, and the supporting element 25 is connected to both ends of the filter element 40. Further, the lens 27 is disposed on the supporting element 25, the circuit board 22, the photosensitive element 21 and the lens 27 is molded to form the molding base 23. At the time of molding, since the closed space 2700 is formed between the lens 27 and the filter element 40, damage of the molding die to the photosensitive element 21 and the filter element 40 can be prevented. Moreover, since the distance between the filter element 40 and the photosensitive element 21 is reduced, the back focus of the camera module 109 assembled by them can be reduced, thereby reducing the height of the camera module 109. On the other hand, the thickness of the camera module 109 is further reduced to some extent, since it is not necessary to provide additional supporting component for the filter element 40.
[0054] Fig. 10 shows a camera module 110 based on another variant embodiment of the preferred embodiment shown in Fig. 7. Different from the camera module 100 in the embodiment described in Fig. 7, in Fig. 10, the structure of the molding main body 232 of the molding base 23 is different. Specifically, as shown in Fig. 10, the molding base 23 of the camera module 110 includes the molding main body 232 and a camera lens mounting section 236, the molding main body 232 and the camera lens mounting section 236 are integrally molded to be connected in sequence. The camera lens mounting section 236 is for mounting the camera lens 10 (the camera lens 10 is not shown in Fig. 10), that is, when the molding photosensitive assembly 20 is used to assemble the camera module 110, the camera lens 10 is mounted at an inner side of the camera lens mounting section 236 to provide a stable mounting position for the camera lens 10. The camera lens mounting section 236 extends integrally upwardly to provide a support fixed position for the camera lens 10 so that no additional components need to be provided to mount the camera lens 10. In other words, the molding base 23 integrally extends upwardly and is internally stepped to mold the lens 27, the supporting element 25, the circuit board 22 and the electronic component 26 respectively, and to support the camera lens 10. It is to be noted that the inner side surface of the camera lens mounting section 236 is flat, so as to be suitable for mounting the unthreaded camera lens 10 to form a fixed focus module. In particular, the camera lens 10 can be fixed to the camera lens mounting section 236 by adhesive bonding. It is also to be noted that the camera lens 10 is mounted on the camera lens mounting section 236 such that the molding base 23 functions as a bracket or a lens barrel in a conventional camera module, and provides a supporting and fixing position for the camera lens 10, but assembly is different from the traditional COB process. The bracket of the camera module of the conventional COB process is fixed to the circuit board in a pasting manner, and the molding base 23 is fixed to the circuit board 22, the supporting element 25 and the lens 27 by an MOL molding process. There is no need of paste fixing process, the molding method has better connection stability and the controllability of the process with respect to the paste fixing, so that the thickness of the camera module is reduced, and further, the molding base 23 replaces the conventional bracket to provide the mounting position of the camera lens 10, which avoids the tilt error caused by the bracket during the assembly, and reduces the cumulative tolerance of the assembly of the camera module. It can be understood by those skilled in the art that, in other variant embodiments, when the filter element 40 needs to be mounted, the filter element 40 may be disposed at the bottom portion of the camera lens 10 in the camera module 100 as described in Fig. 7, it may also be directly mounted on the inner side surface 233 of the molding main body 232 of the molding base 23, as the camera module 108 described in Fig. 8B, and it may also be attached to the surface of the photosensitive element 21 by the supporting element 25 before being molded to form the molding base 23 as shown in Fig. 9. The present invention is not limited thereto.

Light reflected by the object enters the inside of the array camera module 100 from the camera lens 10 and the lens 27 to be subsequently received and photo-electrically converted by the photosensitive element 21, thereby acquiring an image associated with the object. In the present invention, the molding process in which the molding base 23 is molded at the thermohardening lens 27 is defined as a MOL (molding on lens) molding process, and is different from a conventional COB (chip on board) molding process. The disposition of the lens 27 can reduce the optical TTL (the distance from the camera lens plane above a light through hole of the camera lens to the photosensitive plane of the chip), thereby further reducing the size of the array camera module 100 without affecting optical performance to satisfy the need for an electronic device to be provided with a small-sized array camera module 100. At the same time, the disposition of the lens 27 can also reduce stain sensitivity. For example, in one embodiment, 50% of stain sensitivity can be reduced. That is, preferably, the camera lens 10 includes a plurality of lens elements, and the camera lens and the lens 27 form an optical system, and light passing through the optical system are converged to the photosensitive element 21.

In another aspect, in the present invention, the camera lens 10 and the lens 27 form a camera lens assembly, one of the lens of the camera lens assembly becomes an external lens, that is, the lens 27, and the lens 27 is integrally packaged by the molding base 23, so that the size of the camera module can be reduced.
[0102] It is to be understood that a plurality of the circuit boards 22 of the plurality of the molding photosensitive assemblies 20 of the photosensitive assembly may be integrally provided to form a connected circuit board, or may be separate circuit boards.

For example, it is capable of withstanding a molding ambient temperature of 175 °C in the molding process of an embodiment. That is, before the molding process, the high temperature resistant and thermally hardened lens 27 is connected to the supporting element 25 and placed together with the circuit board 22 and the photosensitive element 21 in the molding die, a fluid curing molding material is around the supporting element 25 and the outer surface of the lens 27 to integrally mold the molding base 23, so that the molding base 23 can be integrally molded on the circuit board 22, that is, the molding base 23, the circuit board 22, and the lens 27 forms a unitary structure. It will be understood by those skilled in the art that the lens 27 of the present invention may be not only a thermohardening lens but also a lens with other properties, and the present invention is not limited thereto.
[0104] Further, the lens 27 includes a lens body 271 and a lens periphery 272 disposed around the lens body 271. Since the lens 27 is a precise optical element, the edge of the lens body 271 is thin. The lens periphery 272 disposed at the edge of the lens body 271 and integrally connected is a thickened bracket design capable of carrying the lens body 271 so as not to affect the optical performance of the lens body 271 while enabling the lens body 27 to be integrally molded to be connected to the molding base 23 in a molding die. That is, the lens periphery 272 of the lens 27 is disposed in the non-photosensitive area 213 of the photosensitive element 21 before the molding base 23 is molded, the lens body 271 of the lens 27 is disposed on a photosensitive path of the photosensitive element 21 of the molding photosensitive assembly 20; after the molding base 23 is molded, the molding base 23 embeds the circuit board 22, the non-photosensitive area 213 of the photosensitive element 21, a part of the supporting element 25 and the lens periphery 272 of the lens 27 to form the molding photosensitive assembly 20.

That is, a side of the lens periphery 272 facing the circuit board 22 is defined as the outer peripheral surface 2723 of the lens periphery 272. It is to be noted that the lens body 271 has an lens outer surface 2711 and an lens inner surface 2712. That is, a side of the lens body 271 facing the photosensitive element 21 is defined as the lens inner surface 2712 of the lens body 271, and a side connected to the top surface 2721 of the lens periphery 272 is defined as the outer surface 2711 of the lens body 271.
[0107] Further, after the lens 27 is attached to the supporting main body 251, it is placed in a molding die together with the circuit board 22 and the photosensitive element 21 to perform a molding process. The fluid thermocuring molding material is thermally cured to form the molding base 23, and the molding base 23 embeds the outer side surface 2503 of the supporting main body 251 and the outer peripheral surface 2723 of the lens periphery 271 after being molded. Of course, in other embodiments, the molding base 23 also embeds all or a part of the top surface 2721 of the lens periphery 271 after being molded.

After the light reflected by the object enters the inside of the array camera module 100 from the camera lens 10, it can be received and photo-electrically converted by the photosensitive area 212 of the photosensitive element 21 to acquire an image associated with the object.
[0109] Further, the photosensitive element 21 has a set of chip connectors 211, and the circuit board 22 has a set of circuit board connectors 221, wherein both ends of each of the leads 24 can be respectively connected to each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22, in such a manner, the photosensitive element 21 and the circuit board 22 are connected. In an embodiment of the present invention, each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22 may be a connection disk, that is, each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22 may be respectively in a disk shape for connecting both ends of each of the leads 24 to each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22. In another example of the present invention, each of the chip connectors 211 of the photosensitive element 21 and each of the circuit board connectors 221 of the circuit board 22 may be spherical. For example, a solder paste or other solder material is spotted on the photosensitive element 21 and the circuit board 22 to form the chip connector 211 of the photosensitive element 21 and the circuit board connector 221 of the circuit board 22, respectively. Nevertheless, the shape of the chip connector 211 of the photosensitive element 21 and the circuit board connector 221 of the circuit board 22 does not limit the content and scope of the present invention.
[0110] It will be understood by those skilled in the art that each of the chip connectors 211 of the photosensitive element 21 is disposed at the non-photosensitive area 213 of the photosensitive element 21. In addition, the non-photosensitive area 213 of the photosensitive element 21 has a chip inner side portion 2131, a chip connection portion 2132, and a chip outer side portion 2133, wherein the chip inner side portion 2131 surrounds the photosensitive area 212, both ends of the chip connection portion 2132 respectively extend and are connected to the chip inner side portion 2131 and the chip outer side portion 2132. That is, the area of the non-photosensitive area 213 from a position where the chip connector 211 is disposed to a position of the edge of the photosensitive area 212 is defined as the chip inner side portion 2131, the area of the non-photosensitive area 213 where the chip connector 211 is disposed is defined as the chip connection portion 2132, and the area of the non-photosensitive area 213 from the position where the chip connector 211 is disposed to a position of the outer edge of the photosensitive element 21 is defined as the chip outer side portion 2132. In other words, from the top view of the photosensitive element 21, the photosensitive element 21 is, in order from the outside to the inside, the chip outer side portion 2133, the chip connection portion 2132, the chip inner side portion 2131, and the photosensitive area 212.
[0111] In addition, the circuit board 22 includes a flat chip attaching area 222 and an edge area 223, wherein the edge area 223 is integrally formed with the chip attaching area 222, and the edge area 223 is located on the periphery of the chip attaching area 222. The chip attaching area 222 is used to attach the photosensitive element 21, and the circuit board connector 221 is disposed in the edge area 223. The edge area 223 of the circuit board 22 has a circuit board inner side portion 2231, a circuit board connection portion 2232, and a circuit board outer side portion 2233, wherein the circuit board inner side portion 2231 surrounds the chip attaching area 222, both ends of the circuit board connection portion 2232 respectively extend and are connected to the circuit board inner side portion 2231 and the circuit board outer side portion 2233. That is, an area of the edge area 223 from a position where the circuit board connector 221 is disposed to a position of an edge of the chip attaching area 222 is defined as the board inner side portion 2231, an area of the edge area 223 where the circuit board connector 221 is disposed is defined as the circuit board connection portion 2232, and the area of the edge area 223 from the position where the circuit board connector 221 is disposed to a position of the outer edge of edge area 223 is defined as the circuit board outer side portion 2233. In other words, from the top view of the circuit board 22, the circuit board 22 is, in order from the outside to the inside, the circuit board outer side portion 2233, the circuit board connection portion 2232, the circuit board inner side portion 2231, and the chip attaching area 222. The type of the lead 24 is not limited in the array camera module 100 of the present invention. For example, in a specific embodiment, the lead 24 can be implemented as a gold wire, that is, the photosensitive element 21 and the circuit board 22 can be connected together by a gold wire, so that after the photosensitive element 21 converts the optical signal into an electrical signal, the electrical signal can be further transmitted to the circuit board 22 through the lead 24. It can be understood by those skilled in the art that in other embodiments of the array camera module 100, the lead 24 can also be implemented as any material capable of realizing the transmission of the electrical signal between the photosensitive element 21 and the circuit board 22, such as silver wire, copper wire, etc.
[0112] It is to be noted that each of the electronic components 26 is attached to the edge area 223 of the circuit board 22. Preferably, each of the electronic components 26 is attached to the circuit board outer side portion 2233 of the edge area 223. The photosensitive element 21 and each of the electronic components 26 may be attached to the same side or opposite side of the circuit board 22, such as in a specific embodiment, the photosensitive element 21 and each of the electronic components 26 is attached to the same side of the circuit board 22, and the photosensitive element 21 is attached to the chip attaching area 222 of the circuit board 22, and each of the electronic components 26 is attached to the edge area 223 of the circuit board 22. After the molding base 23 is integrally molded to the circuit board 22, the molding base 23 embeds each of the electronic components 26 to isolate adjacent the electronic components 26 and the electronic component 26 and the photosensitive element 21, so that in the array camera module 100 of the present invention, even the adjacent electronic component 26 is closer, the molding base 23 can prevent adjacent electronic components 26 from contacting or interfering with each other, and the manner in which the molding base 23 embeds the electronic component 26 can also prevent contaminants produced on the surface of the electronic component 26 from contaminating the photosensitive area 212 of the photosensitive element 21, thereby reducing the volume of the array camera module 100 and improving the imaging quality of the array camera module 100. That is, the manner in which the molding base 23 embeds the electronic component 26 in the array camera module 100 of the present invention enabling a small area of the circuit board 22 to be attached with more of the electronic components 26. It is to be noted that the types of the electronic component 26 include, but are not limited to, resistors, capacitors, drivers, and the like.
[0113] Further, as shown in Fig. 57, the array camera module 100 further includes at least two filter elements 40. In the preferred embodiment of the present invention, the filter element 40 is disposed at the bottom of the camera lens 10. That is, the filter element 40 is assembled to the camera lens 10. The optical camera lens inside the camera lens 10 are sequentially arranged, and the filter element 40 is located in the optical path of the camera lens 10. After the molding photosensitive assembly 20 is integrally molded, the filter element 40 and the camera lens 10 are attached to the molding photosensitive assembly 20 to be assembled to form the array camera module 100, wherein the filter element 40 is located in the photosensitive path of the photosensitive element 21. After the light reflected by the object is filtered from the optical camera lens of the camera lens 10 and filtered by the filter element 40, it enters into the array camera module 100, and can be received and photo-electrically converted by the photosensitive element 21. That is, the filter element 40 can filter stray light, such as an infrared portion, from the light reflected by the object in each of the optical camera lens of the camera lens 10, by which imaging quality of the array camera module 100 can be improved.
[0114] It will be understood by those skilled in the art that in different examples of the array camera module 100, the filter elements 40 can be implemented in different types, for example, the filter elements 40 can be implemented as infrared cut filter, a full transmissive spectral filter, and other filters or a combination of multiple filters, for example, the filter element 40 can be implemented as a combination of an infrared cut filter and a full transmissive spectral filter, that is, the infrared cut filter and the full transmissive spectral filter can be switched to be selectively located on the photosensitive path of the photosensitive element 21, for example, when the array camera module 100 is used in an environment where the light is sufficient during the daytime, the infrared cut filter can be switched to the photosensitive path of the photosensitive element 21 to filter the infrared ray of the light reflected by the object and entering into the array camera module 100 through the infrared cut filter. When the array camera module 100 is used in a dark environment such as at night, the full transmissive spectral filter can be switched to the photosensitive path of the photosensitive element 21 to allow the infrared portion of the light reflected by the object and enterring the array camera module 100 to be partially transmitted.
[0115] It is to be noted that the mounting position of the filter element 40 has various variant embodiments in different embodiments. The filter element 40 described in Fig. 57 is disposed at the bottom of the camera lens 10. In other embodiments, the filter element 40 is disposed on top of the molding base 23. Both of these disposing manners are performed by mounting the filter element 40 after the molding photosensitive assembly 20 is molded integrally. In other embodiments, the filter element 40 and the molding photosensitive assembly 20 are assembled together in a molding die. That is, in other embodiments, the peripheral edge of the filter element 40 may be embeded by the supporting element 25 and fixed between the photosensitive element 21 and the lens 27. When the array camera module 100 is not provided with the supporting element 25, the filter element 40 is attached to the photosensitive element 21 and located between the lens 27 and the photosensitive element 21. The latter two disposing manner are in that the filter element 40, the photosensitive element 21, the circuit board 22, the supporting element 25, and the lens 27 are placed together in a molding die, and after being molded by the MOL process, the molding base 23 is formed, and after being attached with the camera lens 10 or a driver 30 driving the camera lens 10, the array camera module 100 is assembled. Various variations in position of the filter element 40 will be disclosed in detail in following embodiments.
[0116] In addition, the filter element 40 may be directly assembled to the top surface of the molding base 23, or the filter element 40 may be assembled to a small lens frame before the small lens frame is assembled to the top surface of the molding base 23, in such a manner that the size of the filter element 40 can be reduced to reduce the manufacturing cost of the array camera module.
[0117] It is to be noted that the lens 27 can be a convex lens and has the function of coverging light. Since the filter element 40 does not cause refraction of light, the lens 27 implemented as a convex lens makes image smaller. The particles (stains) on the filter element 40 tend to cause the photosensitive element 21 to form a large stain point on the image, and the closer to the photosensitive element 21, the larger the imaged stain point is. Therefore, in the MOL process of the present invention, the lens 27 is disposed at a lower portion of the camera lens 10, and the filter element 40 is disposed at a bottom portion of the camera lens 10. That is, the MOL process of the present invention can move the filter element away from the photosensitive element 21 without affecting the convergence of the light of the lens 27 implemented as a convex lens, thereby making the image of the stained spot smaller.
[0118] It is to be noted that, preferably, the lens periphery 272 of the lens 27 has a square step shape.
[0119] It is to be noted that in the MOL molding process of the present invention, the supporting main body 251 also has various variant embodiments. For example, in one embodiment, the supporting main body 251 embeds entire of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner side portion 2231 of the edge area 223, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213; for example, in another embodiment, the supporting main body 251 embeds a part of the lead 24, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213; for example, in another embodiment, the supporting main body 251 embeds a part of the lead 24, the circuit board inner side portion 2231 of the edge area 223, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213; for example, in another embodiment, the supporting main body 251 embeds a part of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner side portion 2231 of the edge area 223; for example, in another embodiment, the supporting main body 251 embeds a part of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner side portion 2231 of the edge area 223 and the chip outer side portion 2133 of the non-photosensitive area 213; for example, in another embodiment, the supporting main body 251 embeds the circuit board inner side portion 2231 of the edge region 223 and the chip outer side portion 2133 of the non-photosensitive area 213; for example, in another embodiment, the supporting main body 251 is formed only at the chip inner side portion 2131 of the non-photosensitive area 213; for example, in another embodiment, the supporting main body 251 is formed only at the circuit board outer side portion 2233 of the edge area 223. Various variant embodiments of the supporting main body 251 will be disclosed in detail in the following embodiments.
[0120] It will be understood by those skilled in the art that variant implementations of the filter element 40 and variant implementations of the supporting main body 251 in the above-described example are merely exemplified in the present invention, and other reasonable variant enbodiments are possible. The present invention is not limited in this respect.
[0121] It is to be noted that, in an embodiment, the array camera module 100 can be implemented as a fixed focus array camera module, wherein the array camera module 100 is assembled to a molding body 232 of the molding base 23 enabling the camera lens 10 to be maintained at the photosensitive path of the photosensitive element 21. It is to be noted that, in an embodiment, the array camera module 100 can be implemented as a zoom camera module, wherein the array camera module 100 adjusts the focal length of the array camera module by changing the distance between the camera lens 10 and the photosensitive element 21. The array camera module 100 is implemented as a zoom camera module as described in Fig. 57. The array camera module 100 further includes the driver 30, wherein the camera lenses 10 are respectively disposed correspondingly to the driver 30, the drivers 30 are respectively assembled to the molding base 23, and the driver 30 is electrically connected to the circuit board 22, respectively, to drive the camera lens 10 moves back and forth along the photosensitive path of the photosensitive element 21 after the circuit board 22 transmits power and control signals to the driver 30, so as to adjust the focal length of the array camera module 100. That is, the camera lens 10 is drivably disposed to the driver 30. It is to be noted that the type of the driver 30 is not limited in the array camera module 100 of the present invention. For example, in another embodiment, the driver 30 can be implemented as any driver capable of driving the camera lens 10 to produce displacement along a photosensitive path of the photosensitive element 21, such as a voice coil motor, wherein the driver 30 is capable of receiving electrical energy and control signals to be in an operational state.
[0122] It is to be noted that when the array camera module 100 is implemented as a fixed focus camera module, the molding body 232 is variably implemented to be a lens bracket for assembling the camera lens 10, The camera lens 10 is directly mounted to the molding body 232 implemented as a lens bracket after the molding photosensitive aseembly 20 is integrally molded, thereby simplifying the assembly process of the array camera module 100. Variations of this aspect of the present invention will be disclosed in detail in the following embodiments.
[0123] That each of the molding photosensitive assemblys 20 are integrally molded by the MOL molding process and assembled to form the array camera module 100 are disclosed in detail in each of the following embodiments.
[0124] In a preferred embodiment of the array camera module 100 of the present invention as shown in Figs 51-57, the bottom surface 2722 of the lens 27 attaches to the top surface 2501 of the supporting element 25, the supporting main body 251 embeds entire of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232 and the circuit board inner portion 2231 of the edge area 223, and the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213, each of the filter elements 40 is disposed at a bottom portion of each of the camera lens 10. In this preferred embodiment of the present invention, each of the camera lens 10 is assembled after each of the molding photosensitive assemblies 20 is integrally molded.
[0125] In some embodiments, in the molding process for fabricating the array camera module 100, a molding photosensitive assembly jointed board 2000 is formed by a board joining operation, and then to be cutted to acquire each of the molding photosensitive assembly 20. Before the molding process is performed to form the molding photosensitive assembly jointed board 2200, a circuit board jointed board 2200 is formed, and the circuit board jointed board 2200 includes a plurality of the circuit boards 22 integrally connected. Further, a molding base jointed board 2300 is integrally formed in the molding process, and the molding base jointed board 2300 after being integral molded includes a plurality of the molding bases 23.
[0126] As shown in Fig. 51, each of the photosensitive elements 21 is attached to each of the chip attaching areas 222 of each of the circuit boards 22, wherein a set of the chip connectors 211 of each of the photosensitive elements 21 and two sets of the circuit board connectors 222 of the circuit board 22 are respectively connected by a set of the leads 24. Each of the electronic components 26 is attached to the edge area 233 of the circuit board 22, respectively. Preferably, each of the electronic components 26 is attached to the circuit board outer side portion 2233 of the edge area 223, respectively. More preferably, each of the electronic components 26 is spaced apart from each other, such that each of the electronic components 26 does not interfere with each other after the array camera module is fabricated.
[0127] Limited to the wire bonding process of the lead 24 and the characteristics of the lead 24 itself, after the chip connection end 241 and the circuit board connection end 242 of the lead 24 are respectively connected to the chip connector 211 of the photosensitive element 21 and the circuit board connector 221 of the circuit board 22, the lead 24 protrudes upward to be above the upper surface of the photosensitive element 21. It will be understood by those skilled in the art that maintaining each of the leads 24 in an initial state during the manufacturing process of the array camera module and process of being used is advantageous for ensuring good electrical property of the leads 24 and the imaging quality of the array camera module.
[0128] As shown in Figs 53 to 56, on one hand, the supporting main body 251 can prevent the connection position of the lead 24 and the chip connector 211 from coming into contact with the thermocuring material for forming the molding base 23, so as to prevent the fluid thermocuring material from causing deformation of the end of the lead 24 for connecting the chip connector 211 or detachment of the lead 24 from the chip connector 211. On the other hand, the supporting main body 251 and the lens periphery 272 of the lens 27 are connected together to isolate the connection position of the lead 24 and the chip connector 211 from the thermocuring material. That is, since the supporting main body 251 and the lens periphery 272 of the lens 27 are connected together, the inner side surface 2502 of the supporting element 25 and the lens inner surface 2712 of the lens body 271 form a closed space 2700, such that during the MOL molding process, the fluid thermocuring material is prevented from entering the closed space 2700, thereby avoiding affecting the light-passing path and also reducing the stain sensitivity. In one embodiment, the supporting main body 251 may be formed by disposing glue on the non-photosensitive area 213 of the photosensitive element 21 and after the glue is initially cured, and after preliminary curing, the lens 27 is further disposed and further cured to finally form the supporting main body 251. After the supporting main body 251 is formed, the inner side surface 2502 of the supporting main body 251 forms the through hole 252, and the photosensitive area 212 of the photosensitive element 21 corresponds to the through hole 252 and the lens body 271 of the thermocuring lens 27. In addition, the supporting main body 251 formed of glue may also have a viscosity for subsequently adhering contaminants such as dust, thereby preventing the contaminants from contaminating the photosensitive area 212 of the photosensitive element 21 to cause a stain point occuring in the photosensitive area 212 of the photosensitive element 21, to further ensure the imaging quality of the array camera module. In other embodiments, the lens periphery 272 of the lens 27 is attached to the supporting main body 251 of the supporting element 25 after the supporting element 25 is fully cured, and the present invention is not limited thereto.
[0129] As shown in Figs 54 to 56, during the MOL molding process, the molding material of the thermocuring material which is implemented in a fluid state is formed into the molding base 23 integrally molded on the circuit board 22 after curing by a molding die 900. In such manner, the size of the array camera module 100 and the assembly error of the array camera module can be reduced, thereby making the structure of the array camera module 100 more compact and improving the imaging quality of the array camera module 100. Moreover, since the lens 27 is disposed on the photosensitive element 21 through the supporting element 25, the optical TTL is reduced, the structure of the array camera module 100 is more compact, and and the electronic device is satisfied with the size of the array camera module 100.
[0130] Specifically, the molding die 900 includes an upper die 901 and a lower die 902, wherein at least one of the upper die 901 and the lower die 902 can be moved to cause the upper die 901 and the lower die 902 being subjected to a clamping operation, and at least one molding space 903 is formed between the upper die 901 and the lower die 902, wherein the molding base 23 is formed by adding the molding material to the molding space 903 and then curing the molding material.
[0131] The photosensitive element 21 and the circuit board 22 are connected by a set of the leads 24, the supporting main body 251 is formed on the non-photosensitive area 213 of the photosensitive element 21 to embed entire of the lead 24, the circuit board outer side portion 2233, the circuit board connection portion 2232, the circuit board inner side portion 2231 of the edge area 223, the chip outer side portion 2133, the chip connection portion 2132 and the chip inner side portion 2131 of the non-photosensitive area 213, the lens 27 is disposed on the supporting main body 251, so that the semi-finished product of the molding photosensitive assembly 20 is fabricated, the semi-finished product of the molding photosensitive assembly 20 is placed on the lower die 902 of the molding die 900, the upper die 901 and/or the lower die 902 of the molding die 900 are operated to clamp the upper die 901 and the lower die 902, so that The molding space 903 is formed between the upper die 901 and the lower die 902, wherein the press-fitted surface 9011 of the upper die 901 is in contact with the lens inner surface 2712 of the lens body 271 of the lens 27, and the lens 27 is supported upward by the supporting main body 251. In this preferred embodiment of the present invention, the exterior of the circuit board 22, the non-photosensitive area 213 of the photosensitive element 21, a part of the supporting element 25, and the outer peripheral surface 2723 of the lens periphery 272 of the lens 27 are located in the molding space 903 of the molding die 900, so that when the molding base 23 is molded in the molding space 903, the molding base 23 embeds the exterior of the circuit board 22, the non-photosensitive area 213 of the photosensitive element 21, a part of the supporting element 25, and the outer peripheral surface 2723 of the lens periphery 272. Preferably, in the molding photosensitive assembly 20 formed as shown in Fig. 52, since the press-fitted surface 9011 of the upper die 901 of the molding die 900 does not completely embed the lens inner surface 2712 of the lens body 271 during the MOL molding process, thus the molding base 23 formed also embeds a part of the top surface 2721 of the lens periphery 272.
[0132] Therefore, it will be understood by those skilled in the art that the molding space 903 of the molding die 900 may be an annular space to form a annular shaped molding base 23 after the molding material is added to the molding space 903 and cured.
[0133] When a plurality of the photosensitive element 21, the supporting element 25, the lens 27, and the circuit board jointed board 1100 are placed in the molding space 903, and when the molding die 900 is in a clamping state, the liquid molding material is fed into and subjected to a curing process to form each of the molding bases 23 integrally molded on the respective circuit boards 22 of the circuit board jointed board 2200 and the photosensitive element 21. These molding bases 23 forms an integral molding base jointed board 2300 such that each of the molding photosensitive assemblies 20 forms a molding photosensitive assembly jointed board 2000.
[0134] It is to be noted that when each of the molding photosensitive assemblies 20 acquired by cutting the molding photosensitive assembly jointed board 2000 is used to fabricate a moving focus camera module, that is, an autofocus camera module, the molding die 900 is further provided with a plurality of driver pin groove molding blocks 9012, for each of the driver pin groove molding blocks 9012, during the molding process, the liquid state molding material does not fill the the position corresponding to each of driver pin groove molding blocks 9012, so that after the curing step, a plurality of the molding holes 231 and a plurality of driver pin grooves are formed in the molding base jointed board 2300 of the molding photosensitive assembly jointed board 2000, the molding base 23 of each of the molding photosensitive assemblies 20 of the splitted fabricated unit is configured with the driver pin groove, so that when the moving focus camera module is fabricated, The pins of the driver 30 are connected to the circuit board 22 of the molding photosensitive assembly 20 by soldering or conductive adhesive attachment, etc.
[0135] It is to be noted that the fluid molding material according to the present invention may be a liquid material or a solid particulate material or a mixed material of liquid and solid particles, it being understood that whether the molding material is implemented as a liquid material or is implemented as a solid particulate material or as a mixed material of liquid and solid particulate, it can be cured to form the molding base 23 after being added to the molding space 903 of the molding die 900. For example, in this specific embodiment of the present invention, the fluid molding material is implemented as a thermohardening material such as a liquid, wherein the molding material is cured after being added to the molding space 903 of the molding die 900 to form the molding base 23. It is to be noted that, when the fluid molding material is added to the molding space 903 of the molding die 900, the curing manner of the fluid molding material is not limited in the content and scope of the present invention.
[0136] It is to be noted that the medium forming the supporting element 25 and the medium forming the molding base 23 are of different materials. The supporting element 25 can be formed by an elastic medium, so that the formed supporting element 25 has a certain elasticity, and the supporting element 25 can also be formed by a rigid medium, and the present invention is not limited thereto.
[0137] As shown in Figs 54 to 56, the supporting main body 251 is disposed along the non-photosensitive area 213 of the photosensitive element 21, and the lens periphery 272 of the lens 27 is closely attached to the supporting main body 251 to form the closed space 2700, such that the supporting main body 251 and the lens body 271 of the lens 27 can block the molding material entering into the closed space 2700 after the molding material is added to the molding space 903 of the molding die 900, that is, avoiding the molding material entering the photosensitive area 212 of the photosensitive element 21, so that after the molding material is solidified to form the molding base 23 and after demolding, the molding base further forms a molding hole 231 to correspond to the photosensitive area 212 of the photosensitive element 21, thereby, subsequently, the molding hole 231 of the molding base 23 allows light to pass through to be received and photo-electrically converted by the photosensitive area 212 of the photosensitive element 21. That is, since the molding material does not enter the closed space 2700, after the demolding, the molding hole 231 is formed between the outer surface 2711 of the lens body 271 of the lens 27 and the press-fitted surface 9011. That is, the molding base 23 includes the molding body 232 and has the molding hole 231, which provides a light path for the optical camera lens 10 and the photosensitive element 21, so that, after the light reflected by the object enters the inside of the array camera module from the optical camera lens 10, the light passes through the molding hole 231 of the molding base 23 to be received and photo-electrically converted by the photosensitive area 212 of the photosensitive element 21.
[0138] As manufacturing the molding photosensitive assembly 20, the photosensitive element 21 is first attached to the circuit board 22, and then the supporting element 25 is formed, and further, the lens 27 is disposed on the supporting element 25, The circuit board 22, the photosensitive element 21 and the lens 27 are molded to form the molding base 23, thereby being molded to form the molding photosensitive assembly 20. At the time of molding, since the closed space 2700 is formed between the lens 27 and the photosensitive element 21, the damage of the molding die to the photosensitive element 21 can be prevented, and since the distance between the lens 27 and the photosensitive elements 21 is reduced, so that the back focal length of the array camera module 100 assembled therefrom can be reduced, thereby reducing the height of the array camera module 100, and on the other hand, there is no need to provide additional supporting components for the lens 27, and thus the thickness of the array camera module 100 is further reduced to some extent. After the molding photosensitive assembly 20 is molded, the driver 30 and the camera lens 10 are assembled on the molding base 23 to be assembled to form the array camera module 100, wherein, in the preferred embodiment, the filter element 40 is disposed at the bottom of the camera lens 10. It will be understood by those skilled in the art that in other variant embodiments based on the preferred embodiment, such as in Fig. 65, after being molded to form the molding photosensitive assembly 20, the camera lens 10 or a lens frame 11 supporting the camera lens 10 is directly assembled on the molding base 23, that is, the driver 30 may not be disposed. The above is by way of example only, and the present invention is not limited thereto.
[0139] Fig. 58B illustrates a variant embodiment of the preferred embodiment based on the present invention, illustrating that the molding photosensitive assembly 20 and the filter element 40 are assembled to form an array camera module 108, in this variant embodiment, the array camera module 108 is similar in structure to the array camera module 100 in the preferred embodiment, except that the filter elements 40 of the array camera module 108 in Fig. 58B are disposed at different positions. In this variant embodiment, the filter element 40 is not provided at the bottom of the camera lens 10 of the array camera module 108, but the filter element 40 is assembled to the top surface the molding base 23, such that the filter element 40 encloses the molding hole 231 of the molding base 23, thereby the light entering the interior of the array camera module from the optical camera lens can be further filtered by the filter element 40 to improve the imaging quality of the array camera module. That is, the top surface of the molding base 23 forms an inner side surface 233 and an outer side surface 234, and in the embodiment shown in Fig. 58B, The plane which the inner side surface 233 of the molding base 23 is located may be lower than the plane in which the outer side surface 234 is located, so that the top surface of the molding base 23 forms a stepped shape surface, that is, the inner surface 233 of the molding base 23 is located at a lower plane than the outer surface 234 to form a groove 235 of the molding base 23, wherein the filter element 40 assembled to the inner side surface 233 of the molding base 23 is accommodated within the groove 235 of the molding base 23, the driver 30 is assembled to the outer side surface 234 of the molding base 23 to enable the optical camera lens 10 assembled to the driver 30 to be further held in the photosensitive path of the photosensitive element 21, thereby producing the array camera module 108. It will be understood by those skilled in the art that in other embodiments, the inner side surface 233 and the outer side surface 234 of the molding base 23 are in a same plane to allow the top surface of the molding base 23 forms a flat plane, wherein the filter element 40 is assembled to the inner side surface 233 of the molding base 23, and the driver 30 or the camera lens 10 is assembled to the outer side surface 234 of the molding base 23, or the camera lens 10 is assembled directly to the outer side surface 234 of the molding base 23. The above structure of the molding base 23 of the present invention is merely an example, and the present invention is not limited thereto.
[0140] As manufacturing the molding photosensitive assembly 20, the photosensitive element 21 is first attached to the circuit board 22, and then the supporting element 25 is formed, and further, the lens 27 is disposed on the supporting element 25, so that, the circuit board 22, the photosensitive element 21, and the lens 27 are molded in a molding die to form the molding base 23, thereby forming the molding photosensitive assembly 20. Further, the driver 30 and the camera lens 10 are assembled after the filter element 40 is assembled to the top surface of the molding base 23, thereby assembling and forming the array camera module 108.
[0141] An array camera module 109 according to another variant embodiment of the preferred embodiment of the present invention is described, as shown in Fig. 59, the structures of the array camera module 109 in the variant embodiment and the array camera module 100 in the preferred embodiment are similar, except that the disposition and assembly order of the filter elements 40 of the array camera module 109 in Fig. 59 are different. In the preferred embodiment of Fig. 57, the molding photosensitive assembly 20 is molded and formed first, and then the filter element 40 disposed at the bottom inside the camera lens and the camera lens 10 are assembled together on the molding base 23. The array camera module 109 of this variant embodiment shown in Fig. 59 is such that the filter element 40 and the lens 27, the supporting element 25, the photosensitive element 21, and the circuit board 22 are placed together in a molding die to form the molding base 23, and then the driver 30 and the camera lens 10 are attached to the molding base 23. Specifically, in this variant embodiment shown in Fig. 59 of the present invention, the filter element 40 is laminated on the photosensitive element 21. A surface attach process can be used here. In order to enhance the stability of the filter element 40 in the photosensitive element 21, in an embodiment, the edge of the filter element 40 is fixedly connected by the supporting element 25 and is attached to the photosensitive element 21, thereby the filter element 40 is fixed between the supporting element 25 and the photosensitive element 21. The outer side surface 2503 of the supporting main body 251, the outer peripheral surface 2723 of the lens periphery 272 are molded to the molding base 23, the supporting element 25, the photosensitive element 21, and the lens 27, the circuit board 22 and the electronic component 26 are molded by the molding body 232 of the molding base 23. It is to be noted that in this embodiment, the filter element 40 covers the photosensitive element 21, and the photosensitive element 21 is isolated from the closed space 2700 and the external environment, thereby avoiding damage of the photosensitive element 21 and preventing dust entering the closed space 2700 from contacting the photosensitive element 21, reducing stain sensitivity.
[0142] When the molding photosensitive assembly 20 is fabricated, the photosensitive element 21 is attached to the circuit board 22, and the filter element 40 is attached to the photosensitive element 21, and then the supporting element 25 is formed, and the supporting element 25 is connected to both ends of the filter element 40, further, the lens 27 is disposed on the supporting element 25, the circuit board 22, the photosensitive element 21 and the lens 27 is molded to form the molding base 23. At the time of molding, since the closed space 2700 is formed between the lens 27 and the filter element 40, damage of the molding die to the photosensitive element 21 and the filter element 40 can be prevented. Moreover, since the distance between the filter element 40 and the photosensitive element 21 is reduced, the back focus of the array camera module 109 assembled therefrom can be reduced, thereby reducing the height of the array camera module 109. On the other hand, the thickness of the array camera module 109 is further reduced to some extent because there is no need to provide additional supporting elements for the filter element 40.
[0143] An array camera module 110 based on another variant embodiment of the preferred embodiment shown in Fig. 57 is shown in Fig. 60. Unlike the array camera module 100 of the embodiment described in Fig. 57, in Fig. 60, the molding body 232 of the molding base 23 has a different structure. Specifically, as shown in Fig. 60, the molding base 23 of the array camera module 110 includes the molding body 232 and a camera lens mounting section 236, the molding body 232 and the camera lens mounting section 236 are integrally molded in turn to be connected. The camera lens mounting section 236 is used to mount the camera lens 10 (the camera lens 10 is not shown in Fig. 60), that is, when the molding photosensitive assembly 20 is used to assemble the array camera module 110, the camera lens 10 is mounted inside the camera lens mounting section 236 to provide a stable mounting position for the camera lens 10. The camera lens mounting section 236 integrally extends upwardly to provide a supporting fixed position for the camera lens 10 so that no additional components need to be provided to mount the camera lens 10. In other words, the molding base 23 integrally extends upwardly and is internally stepped to mold the lens 27, the supporting element 25, the circuit board 22, and the electronic component 26, respectively, and to support camera lens 10. It is to be noted that the inner side surface of the camera lens mounting section 236 is flat, so as to be suitable for mounting the unthreaded camera lens 10 to form a fixed focus module. In particular, the camera lens 10 can be fixed to the camera lens mounting section 236 by adhesive bonding. It is also to be noted that the camera lens 10 is mounted on the camera lens mounting section 236, such that the molding base 23 functions as a bracket or a lens barrel in a conventional array camera module, and provides a supporting and fixing position to the camera lens 10, but assembly is different from the traditional COB process. The bracket of the array camera module of the conventional COB process is fixed to the circuit board in a pasting manner, and the molding base 23 is fixed to the circuit board 22, the supporting element 25 and the lens 27 by an MOL molding process. There is no need of the paste fixing process, the molding manner has better connection stability and the controllability of the process with respect to the adhesive fixing, so that the thickness of the array camera module is reduced, and further, the molding base 23 replaces the conventional bracket to provide the mounting position of the camera lens 10, which avoids the tilt error caused by the bracket during adhesive assembly, and reduces the cumulative tolerance of the assembly of the array camera module. It can be understood by those skilled in the art that, in other variant embodiments, when the filter element 40 needs to be mounted, the filter element 40 may be disposed at the bottom portion inside the camera lens 10 in the array camera module 100 as described in Fig. 57, and may also be an array camera module 108 as described in Fig. 58B, and the filter element 40 is directly mounted on the molding body 232 of the molding base 23, and may also to be attached to the surface of the photosensitive element 21 by the supporting member 25 before be molded to form the molding base 23 as shown in Fig. 59. The present invention is not limited by this.
[0144] It can be understood that, in order to more clearly illustrate various variant embodiments of the array camera module of the present invention in the drawings, the array camera module of Fig.s 65 to 98 only shows the portion of the variant implementation. The present invention is not limited in this respect.

The molding body 232 is integrally molded to embed the electronic component 26, the edge area 223 of the circuit board 22, the outer side surface 2503 of the supporting element 25, and the outer peripheral surface 2723 of the lens periphery 272, thereby forming the molding photosensitive assembly 20. It will be understood that the molding body 232 may also embed a part or all of the top surface 2721 of the lens periphery 272 to enhance the stability of the lens 27.
[0146] It is to be noted that the camera lens 10 implemented as a fixed focus module in the embodiment of Fig. 65 is supported by the lens frame 11, and the inner side of the lens frame 11 is threaded, but it can be understood, in other embodiments, the lens frame 11 may be unthreaded inside, and the present invention is not limited thereto.
